one is a CRX style box.. and the other is built more to specs

4.081 cubes with 4 4" external at 18" long @ 39.04hz .. external aeros

(ports will likely get shortened as testing and tuning comes into play so tuning will go up)

-or-

6.154 cubes.. internal aeros .. 4 4" and 6" long .. 46.51hz for spl.. 18" long for daily @ 32.65hz

(tuning could change if the car peaks lower than 56hz)

box 1.
Smaller box,
more power,
And i bet your car peaks in the high 40's, low 50's

I would go with the 2nd box. Even though the first box would be fun to play around with.

im thinking low 50s.. but its a wagon so it may be lower.. seems larger cars peak lower.. of course each car has two peaks

amp will be the SS6500d @ 0.5ohm for now

ive just never messed with a crx style.. i don't think ima have time to build before the show tomorrow so i may just mod the box thats in there and tune it lower..

im going to sweep a sealed 15 and find the note with everything in the car.. should put me in a close target range to tune the new box too
